When we dream about the future, many like to think of owning a personal flying car. The advantages are obvious. This technology would allow total freedom of movement. We could fly at 480 km per hour, avoiding traffic lights and busy roads.However, some people believe there will be problems with traffic control. If the cars become popular, there is likely to beair traffic jam. Another big problem is mechanical failure. What will happen if the cars stop working? These are problems we must expect if flying cars become a reality.

Three-dimensional printing is another new technology with excitingpossibilities. 3D printers are used to build an object with liquid plasticThey build the object layer by layer until it is complete. Car companiesalready use 3D printers to make life-size models of car parts, and medicalcompanies use the technology to make man-made body parts. As we move into the future, 3D printing will revolutionize the way we shop, the way we manufacture and the way we treat sick people. The disadvantage is that such equipment will be extremely expensive.
